NEWS YOU CAN USE: Only Whey, Not Soy Works ‘Wheytloss Wonders’.
The study at hand is only one out of many experimental trials which refute the notion that plant proteins are healthier and eating plant instead of protein from animal sources would help you lose weight and improve your body composition. The latter is a myth that’s based on questionable epidemiological data, where confounding factors such as the “pizza salami = meat” factor (i.e. the way the meat intake is estimate) are hard to control.
Since I hope that we all put more faith in hard experimental vs. “soft” epidemiological data, it should be obvious that anyone (including your vegan friends) who is planning to lose body fat and improve his / her body composition is much better off with whey vs. soy protein; and that not just as a replacement for a complete meal, but rather as an addition that increases the total protein content of the diet and reduces the food and energy intake on ad-libitum meals, when the shake is consumed 30 minutes before a meal.
